This study refines the existing large and medium office models from the U.S. DOE Commercial Prototype Building Models (CPBM) to accommodate the purpose of occupant-centric control (OCC) implementation and evaluation. Firstly, a detailed rezoning plan was created to add the zoning diversity (e.g., closed office, open office, conference room) to the original medium and large office models in the CPBM. Next, a unique set of dynamic occupancy schedules were generated using a statistical tool for each room to represent the occupancy variation. Then, two OCC cases were generated utilizing the occupancy presence sensing and occupant counting technologies. Finally, the refined models were extended to different versions of ASHRAE standards (e.g., ASHRAE Standard 90.1-2004, 2007 and 2010) and various U.S. climate zones following the code requirement. The simulation results suggested that the presented OCCs could achieve huge energy savings for the HVAC system, especially in cold climates.
